HOSE-WASHER.

Application filed December 10, 1909.

To @ZZ whom t may concern:

Be it known that l, HARRY l?. Hennen, a citizen of the United States, residing' in Los Angeles, county of Los Angeles, State of California, have invented a new and useful Hose-Flasher, of which the following is a specification. l

The object of my invention is to provide washer for hose couplings which will afford a perfect paclringbetween the two members of the hose coupling' when the same are screwed together, and which will not be-liable to fall out or become displaced when the male member is unscrewed from the female member of the coupling. Y

The accompanying drawings illustrate my invention- Figure l, is a view showing` a female member of a hose coupling in section with my washer in place; Fig. "2, is a side elevation of the preferred form of my invention; F ig. 3, is a. plan of the form shown in Fig. 2; Fig'. e, is another form of the invention.

l is the female member of a hose coupling', 2 is my improved washer which is made preferably from resilient material such as india rubber vulcanized to the desired degree of hardness, 3 indicates peripheral corrugations around the washer body, and 4lis a shoulder in the hose coupling.

In manufacturing washers according to my invention l prefer to employ a hollow bar of elastic material such as vulcanized rubber of the desired diameter and having a perforation suitable to be cut into washers of the proper thickness. Such bar is placed in a lathe or other suitable machine and the same is indented oreut to form the corrugations 3 in the periphery of the washers. These corrugations may be made in any desired manner by cutting; or indenting the surface of the bar and may be formed spirally around the bar or may be formed parallel with each other as indicated in Fin. 4l. l prefer to form the corrugations spirally as shown in Fig. 2 and when so formed, and the washer is seated within the hose coupling' member 2, the corrugations will register with the threads of the hose coupling member and prevent its displacement. lWhen the washer is provided with parallel corrugations as shown in Fig. 4c, the cor- Patented @et i9, limiti.

Serial No. 532,478.

rugations will cross the threads of the hose member and the threads of the hose member will indent the corrugations in crossing the same, it beine; remembered that the Washer 2 being' of a'resilient nature will press outwardly and fill thethreads and form a tight packing' when the male member of the coupling is screwed down upon the washer.

ln use, the washer will be inserted within the hose coupling` member 2 and will be seated .in the ordinary manner, after which the other hose member will be screwed into the member 2 and against the wash-er which will cause the corrugations on the washer to firmly engage with the threads in the hose coupling member and be retained within such member when themale member is unscrewed from the female member. ln placing,r the washer within the hose coupling member, the same may be pushed inward by the operator until the same is seated, or when the form shown in Fig. 2 is employed, the same may be run down in the threads of the female member until the same is seated.

What l claim is:

l. As a new article of manufacture, a self-retaining` hose washer formed of flexible, elastic, and resilient material; said washer havinp; therethrough a central opening', and provided on its external periphery with a plurality of integral corrugations throughout the length of the washer, forming' a series of thin, highly iieXible projections to engage the threads of a hose coupling'.

2. As a new article of manufacture, a selfretaining' hose washer formed of ieXible, elastic, and resilient material; said washer having' therethrough a central opening, and provided on its external periphery lwith a plurality of integral, continuous corrugations which encircle the periphery throughout the length of the washer and form a series of thin, highly flexible projections to engage the threads of a hose coupling.

3. As a new article of manufacture, a selfretaining.;` hose washer formed of flexible, elastic, and resilient material; said washer having therethrough a central opening7 and provided on its external periphery with a plurality of integral, continuous corrugations formed by a continuous spiral which rlins from one end of the Washer to the my hand at Los Angeles, California, this other and forms a series of thin, highly- 2nd day of December, 1909. flexible projections adapted to make threaded HARRY P HEPRO engagement with the screw threads of a hose 'L 5 coupling' when the Washer is forced or screwed into place ina coupling.
